The U.S. Supreme Court ruled on Monday that federal law protects LGBT workers from job discrimination and they can sue for workplace bias, issuing a major civil rights decision.

The 6-3 ruling represented the biggest moment for LGBT rights in the U.S. since the Supreme Court legalized same-sex marriage nationwide in 2015. 

In Monday's new ruling, the justices decided that gay and transgender people are protected under Title VII of the Civil Rights Act of 1964, which bars employers from discriminating against employees on the basis of sex as well as race, color, national origin and religion.
